An Acronym for Unix FileSystem.
It was originally developed from the first versions of UNIX at AT&T. The FileSystem reached its current status in the 4.x BSD distributions. It it currently used in FreeBSD, NetBSD as well as OpenBSD and the Solaris Operating Environment. The Linux Kernel only includes experimental support.
FreeBSD versions 5.0 introduced UFS2, which allows soft updates, a more efficient method of writing FileSystem MetaData, as well as support for volumes over 1TB in size.
